Has any of the owners of the 40AX xte have the same issue or am I loosing it.

Did you flush the black tank or just drain it? The sensors are notorious for inaccurate readings (including reading full when its empty).

Actually I dumped the black tank and backwashed it, the monitor panel had 1 light light and the toilet display in the half bath was green

My 2018 Windsport 29m has the bathroom sink draining into the black tank. When I realized it and asked Thor, their answer was because of limited drain pipe routing to the gray tank. I actually prefer this because we ALWAYS fill up the gray before the black tank, just two of us and also easy to put a couple gallons of water in black tank when you need to recharge the tank with a new treatment pod.
